6.3.7 Copeland Discus with Core-
Sense Protection
The Discus application can monitor semi-hermetic
compressors using the MODBUS network on E2 versions
3.01 and above. The E2 monitors and records semi-her-
metic compressor information. The Discus application has
extensive logging capabilities that record a compressor’s
Run History, Fault History, and Alarm Status.
The Copeland Discus is supported on E2 RX-300, CX-
400 and above.
6.3.8 Light Commercial Thermo-
stat
The Light Commercial Thermostat communicates with
the E2 using the MODBUS network. The thermostat will
enable the E2 to read status information from the device as
well as send operational setpoints to the device. The ther-
mostat is available on E2 versions 3.02 and above.
6.3.8.1 Thermostat Inputs
The E2 application will provide support for external
real time inputs to the thermostat. These inputs are:
•Zone Temperature
•Minimum Damper Position
•Outside Air Temperature
•Inside Humidity
If these inputs are connected to valid values, they are
sent to the thermostat to be used in place of any locally
connected sensors of the same type. If local sensors are
present and meant to be used, the associated inputs on the
E2 application should be left disconnected.
6.3.8.2 Advisory and Alarms
The Light Commercial Thermostat also supports diag-
nostic functions. When a diagnostic code is sent to the E2
from the thermostat, the E2 application will identify the
code and generate the corresponding advisories in the
advisory log.
Diagnostic Alarms
Each of these configurable diagnostic alarms in the E2
can be set to Disabled, Failure, Alarm, or Notice with an
accompanying priority setting.
The diagnostic alarms supported are:

Diagnostic Alarm Descriptions E2 Advisory
Heating Two Hours Thermostat did not see a rise in supply temperature when heating was
called for.
Heating Problem Detected
Heat Continuous In heat or backup heat mode, thermostat opens latching relay contacts if
temperature is over 10°F above setpoint.
Heat Shutdown – Temp too high
Temperature Sensor Fail If heating or cooling is engaged, and either the indoor temperature sensor
reading or the supply air temperature sensor reading starts moving the
opposite way faster than it was before the heating or cooling was engaged,
the thermostat reports a diagnostic message, and shuts down the operation.
Incorrect Sensor Wiring
Stuck Key A stuck key (closed) has been detected on the thermostat. Stuck Key Detected
Unexpected Temperature
Rise
Thermostat has detected a failure of the internal space temperature sensor,
or the O/B wiring is incorrect.
Failed Sensor or Bad Wiring
